I agree with the author that there are some projects which really worth investing, and besides we all need new blood in crypto industry and it will be impossible without ICOs. Crypto market will never develop without new tokens.
Of course not all ICO projects are scam. If there are no trustworthy ICO project, I don't think any investor will keep investing in ICO anymore. But for now, ICO project is still a really good way to earn money for professional investors only but with new and amateur investors, I don't think it's a good choice
